wl-:FT-FORK FOR Looms.

SPECIFICATION forming part of Letters Patent No. 513,928, dated January 30, 1894.

Application led May 29. :1893. SerialNo. 475.890. (No model.)

T0 all whom t may concern:

Be it known that I, WILLIAM HINCHLIEFE, of Huntsville, county of Madison,State of Alabama, have invented an Improvement in Weit-Forks for Looms, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts. Y

This invention has for its object to provide a weft fork having detachable tines; and also to enable the weft-fork bot-h body and tines, to be removable from the usual rocking pin of the weft-fork slide withoutremoving said Figure 1, in perspective, shows a weft-fork embodying my invention, together with part of the slide in which it in practice will be mounted to tip, the said slide being represented in dotted lines and as transparent; Figs. 2 and 3, a section and plan view of a modified form of fork; Fig. Il, yet another modification.

In the drawings, A represents a slide-bar such as commonly employed to sustain the rocking pin or pivot a, of the weft-fork.

I have shown my improved weft-fork b as made from sheet metal, the metal being brought into shape preferably by dies, the forks having any desired number of prongs to meet the weft. The weft-fork is composed of a pronged front end and al tail-piece, and in Fig. 1, the front and tail-pieces are made of separate pieces, the tail-piece b being represented as a box-likeA plate, into which the shank of the prong piece isinserted as in said Fig. l where it is held by a suitable set screw b2. The tail-piece has open loops or eyes b3 to embrace the rocking pin a and to permit the fork and tail-piece to be removed from the rocking pin when desired. The free end of the tail-piece has a lip b4 adapted to be engaged by the usual weft-hammer, not shown.

In the modi'ication Figs. 2 and 3, the boxlike end of the tailpiece is omitted, but the tail-piece c has an open loop at c for the reception of the rocking pin c2, and the fork d is connected to the tail-piece by suitable screws 2, 2, the shank of the fork being preferably slotted as at 3 to permit the fork to be adjusted on the tail-piece with reference to the rocking pin `c2, to thus enable the fork to be nicely balanced.

In the modification Fig. 4, the forkf and tail-piece f are all in one piece,but provided with the open eyef2 to embrace the rocking pin f3, a screw f4 being added to cross the rocking pin and keep the fork and tail-piece in place. The rocking pins a, c2 and]3 are supposed to be all alike, and in practice they will all be supported in the slide, and in all the forms of my invention the fork and also the tail-piece may be removed from the rocking pin without disturbing the latter.

One important feature of my inventionlies in the fact that the fork may be readily re- Amoved when desired without disturbing the rocking pin.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a weft-fork slidebar and its stationary rocking pin, of a tailpiece having an open eye to partially embrace the said pin whereby the tail-piece may be removed from the slide Without disturbing the said pin, substantially as described.

2. A tail-piece having an open eye to partially embrace a rocker pin, and a sheet metal fork made adjustable on said tail-piece, combined with a weft fork slide bar having a stationary rocking pin, to operate, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

WILLIAM HINCHLIFFE.
